# S4 method for missing,character,character
moduleMetadata(module, path, defineModuleListItems)

# S4 method for missing,character,missing
moduleMetadata(module)

# S4 method for ANY,ANY,ANY
moduleMetadata(sim, module, path)

Arguments

sim	A simList simulation object, generally produced by simInit.
module	Character string. Your module's name.
path	Character string specifying the file path to modules directory. Default is to use the spades.modulePath option.
defineModuleListItems	A vector of metadata entries to return values about.

Value

A list of module metadata, matching the structure in defineModule.
